your spending a dollar trying to save yourself a dime, just masturbate onto your stomach and wipe it up
Either let it fly onto the floor or use a condom. A condom with a little bit of lube inside feels awesome anyway!!!
I always masturbate in my chair in front of my computer. I'm not much of a "shooter" anymore so all I do is spread a towel on the floor under my computer desk so that when I cum I let it drip down my cock and balls and let it drip off onto the towel on the floor. Then I clean the streams of cum off my cock and balls with the towel.
Try it outside in a very private area, when no one else is home. The lawn / grass would thank you for your kind donation !
lol just cum on your damn shirt/pants then splash some water on it, wipe it off, good to go. it'll dry in a few minutes.
